ROUTER-PLANE.

SPECIFICATION forming part of Letters Patent No. 350,352, dated October 5, 1886.

Application tiled February 20, 1886. Serial No. 192,667. (No model.)

To all whom it may concern:

Be it known that I, JOHN L. DE HUFF, of Reading, in the countyof Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Router-Planes, of which the following is a specification.

My invention relates to planes used by pattern or cabinet makers, and partieularly'to what are known as router-planes?7 employed for grooving or channelling woodwork.

It is the object of my invention to construct a device of the character mentioned which shall be more serviceable than those heretofore employed, in that it will not be liable to become clogged or obstructed in its operations by shavings,-may be readily adj usted to tools or planeirons of different forms and sizes, and *may have other points of advantage, all as hereinafter fully described, and subsequently pointed out in the claims.

In the drawings hereto annexed and forming a part of this specification, Figurel represents a top plan View of myimproved router-plane, one handle being shown as removed; Fig. 2, a front View; Fig. 3, a vertical section on the line .e x, Fig. 2; Fig. 4,- a section on the line yy, Fig. 2; and Fig. 5, au end View.

Similar letters of reference indicate similar parts in all of the figures.

In the drawings,a represents the stoel; of the plane, '0, the sole thereof, c, the handles, and d the cutting-tool or plane-iro11. As shown, the sole is formed in two equal seetions, adjustable longitudinally on the stock` by means of a scrcw-threaded stem or stud, c, secured. to the upper surface of each sole-section @,which stem or stud projects through an elongated slot, f, inthe stock, and upon which the handles are secured by being screwed thereon, as clearly represented in Figs. 3 and 5. A washer is preferablyinterposed between the base of the handle and the upper surface of the stock. By the construction described the stem or stud c serves the purpose of attaching the handle to the stock, and, in connection with the handle, of clamping the sole-sections b to the stock proper at any point thereon n within the limit of its adjustment, and an open channel, 0*, from, front to rear of the plane, is formed between the sole-sections. Each solc section is provided ou its upper surface with ribs g,'extending along the sides thereof, as Y shown in Figs. l and 5, and the undersurfaee of the stock proper, at both sides of its center, is provided with ribs h h', the sides of which ribs are adapted to slide in correspondinglyshaped grooves formed in the ribs g on the sole. (See Fig. 4.) Rib 7L on the under surface of the stock is constructed to move between the ribs g to form a close joint or connection between the stock and sole7 and thus avoid liability of shavings becoming caught between the parts and obstructing the operations of the device. Any other construction and arrange-Y ment of ribs g and 7a to answer the samepurpose would be within the scope of my invention.

The stoel: is cast or otherwise formed with a chamber, l,.at its centen-and with lugs j y' projecting laterally from above and below said chambered part. Holes L and Z are bored through the upper and lower portion of the ehambered portion, and rodm, fitted to turn in holes 7c, is extended therethrough, as clearly shown in Fig. 4. Said rod is screw-threaded on that portion passing through the chamber, and is so stepped in the lower portion of the stock proper as to turn or rotate in holes 7.', but not to move vertically therein, a head, iz, being secured to the upper end of said rod, whereby it maybe rotated. Theholeslin the lugs j are adapted to receive the stem o of the planer-iron or cutting-tool. The screw-threaded portion of the rod m passes through a corresponding screw-threaded hole in a traveler, p, within chamber i, whereby by turning said rodsaid traveler may be raised or lowered thereon wit-hin said chamber. Said traveler is provided with a split clamp extension q, through which the stem of the plane-iron is adapted to pass, and in which it is adapted to be clamped or secured by means of a bolt `passing through cars i' of said split clamp portion.

It will now be understood that a cutting tool or iron of any character may be secured in the clamp of the traveler at any horizontal ,angle therein, and adjusted by means of the rod m to any desired height, while the sole partsb b of the stock can be adjusted to a position as close to or far from the tool as the size orform of the cutting portion of the planer-iron may require,

Experience has demonstrated that a routerplane constructed in accordance with my invention is serviceable in the highest degreein all the uses for which a tool. of that character is designed, and that there is no liability of the device becoming clogged or obstructed in its operation by shavngs or ehi ps cut freni the material being operatei'l. upon. The edges of the soles are given a sloping forni., and a gage, s, grooved to ft said edges, is secured thereon by means ofthumb-sercws t, as shown in the drawings. This gage is adapted to operate against the edge of the material being groovcd or channeled, by which inf-ans the groove may be formed in different pieces, the material at preeiselyihe saine distance from the edge, all as will be readily nnderstoml by those skilled in the art.

Il', do not confine myself or expect to be confined to the precise forni and arrangement of parts shown and described, as these may be changed without departing from the spirit of the invention.

nWhatl claim is A router-plane haring its sole portion formed in two parts, one or both of said parts being adjustable longitmlinally on the stoel; to and from the side or sides ofthe planeriron or enttingvtool, as set forth.

2. A router-plane provided with a planeriron or cutting-tool adjustable vertically therein, and having its sole portion formed in two parts longitudinally adj ustable on both sides of the planer-iron or cutting-tool, as set forth.

The router-plane having flanges -L t, 35*

proper, studs or rods secured to the upper surface of said sectional sole parts and projecting through said slots, means for securing the handles of the planer to said studs and at the saine time adjusting the sole'parts at any desired point on the stoel; on one or both sides of the planer-iron or cuttingtool, as set forth.

5. The combination, with the stoel: pro vided with the ehalnber i and lugs j,-having he holes l.: and l formed therein, of the rod m, traveler p, provided withv the split e'lmnpporA tion q, having ears n, the clampingboltin said ears, and the cutting-iron d, as set forth.

ln testimony whereof l. have signed my name lo this speeilieation, in the presence of two subscribing witnesses, this 10th day ol' Feb- 6c ruary, 18845.
